Best-practice tips

• Exhale slowly: A steady, controlled exhale maximizes contact time with the filter media.
• Aim straight: Keep the mouthpiece level and centered for the most efficient pass-through.

• Know when to replace: If you notice increased resistance or reduced performance, it’s time for a new unit.

Frequently asked questions

Does it make sessions completely odor-free?
It dramatically reduces exhale odor and visible smoke. As with any exhale filter, extremely large clouds or strong terp profiles may leave faint residual scent, especially in unventilated rooms.

Can I use it with vapes as well as bongs?
Yes! Houdini is designed for exhale filtration regardless of the device you’re using.

How long does it last?
MJ Arsenal advertises the Houdini being able to filter 200 exhales. Lifespan depends on exhale size and frequency. Replace when you feel increased resistance or notice reduced odor control.

Is it rechargeable or electronic?
No power needed—just exhale through it.
